TECHNICAL FIELD

The described technology is directed to the field of techniques for building and supporting online communities.

BACKGROUND

While online communities are becoming increasingly popular, members of conventional online communities tend to participate in them almost exclusively by accessing a web site provided by the online community using a web browser. This mode of participation can tend to limit the usefulness of and level of interest in conventional online communities.

In view of the foregoing, techniques for participating in an online community by performing interactions in the real world would have significant utility.

DETAILED DESCRIPTION

A software and/or hardware facility that enables participation in an online community using visual machine-readable symbols (“the facility”) is described. In some embodiments, users of the community can interact with a community website to create content items that are available to some or all members of the community. For example, users may create restaurant reviews, musical artist descriptions, songs, documents, or virtually any other textual, graphical, audio, video, or other content. For each created content item, the facility assigns an identifier that uniquely identifies the content item among all of the content items created in the community, generates a two-dimensional barcode encoding the identifier, and permits the creating user to print out the barcode, and/or incorporate the barcode into a larger document that can be printed. For example, a user may create a restaurant review document for a restaurant, and tape a printed copy of the resulting barcode to the doorframe of the restaurant, or create a description of a band and incorporate the assigned barcode into a poster announcing an upcoming performance by the band.

When another user of the community encounters such a printed barcode, s/he can use an application installed on his or her cameraphone to optically capture and decode the barcode, communicate the user's capture of the barcode to a server, and optionally download the content item to the phone. In some embodiments, the server maintains a count and/or list of users who have captured each barcode. When the capturing user later visits the collaboration website, s/he can select the content item from a. list of all of the content items whose barcodes the user has captured and display and interact with the content item, such as by commenting on it, annotating it, etc.

In some embodiments, the facility enables a user to encode other types of information into a barcode that can be read and decoded by the facility's cameraphone application. For example, a first user may encode a phone number into a barcode. When this barcode is captured by a second user's cameraphone, the cameraphone can call the encoded phone number. The first user may similarly encode an email address that the second user's cameraphone can use to address an email message.

In some embodiments, the facility displays advertising messages to a user, either on the user's cameraphone or within the context of the community web site, that are targeted based at least in part upon the set of symbols captured by the user.

In some embodiments, the facility supports a number of other special-purpose symbols, such as a symbol that a user may capture in order to add his or her email address to an email list, or otherwise join a discussion group about a particular subject. Also, in some embodiments, a user may capture a symbol from a shelf tag for an item at a store to receive a coupon for that item. In some cases, the facility can encode information into a symbol that is displayed on the display of a smart phone, such as a symbol encoding a coupon redemption code.

By performing in some or all of the ways described above, the facility enables the community to incorporate real-world interactions into the participation of users in the community.

FIGS. 1-23 are user interface diagrams showing typical displays presented the by facility as part of the community web site.

FIG. 1 shows a display presented by the facility in order to register a new user for the community. The display 100 includes user interface controls for entering information such as the following: a user name 101 used to identify the user; a password 102 used by the user to authenticate his or her identity to the facility; an email address 103 at which the user can receive email directed to the user; an indication 104 about whether the facility may share this email address with other users of the facility; a telephone number 105 for the user's smart phone; a mobile carrier 106 that provides wireless service to the cell phone; a geographic locale 107 in or near which the user resides or frequently visits; an indication 108 that the user has read agreements relating to the use of the facility; and a photo 110 portraying the user. After entering this information, the user selects control 109 in order to create a profile.

In response, the facility generates a confirmation code and transmits it to the user's cameraphone, such as in a text message or a voicemail message. When the user receives the confirmation code on his or her cameraphone, the user enters it into a subsequent display generated by the facility (not shown) to complete the creation of the user's profile.

In many cases, the user proceeds to use the community web site to download a symbol capture and processing program for installation on the user's smart phone. As part of the installation of this program, the user's user name or another identifier for the user is solicited from the user, and stored in a location in the cameraphone that is accessible to the capture program.

FIG. 24 is a network diagram showing some of the devices that are used in connection with some embodiments of the facility. A browsing client such as desktop computer, a laptop computer, a personal digital assistant, or another device capable of executing a web browser includes at least a web browser 2411 and a display 2412. A user of the browsing client can connect via the Internet 2420 to a server 2430 hosting the online community website and the facility. The server contains data and logic 2431 for the community website, a content store 2432 for content created and/or uploaded as part of a discussion, and a symbol generator module 2433 for generating computer-readable symbols. In various embodiments, the facility uses a variety of symbol generation and decoding schemes, such as the Data Matrix scheme promoted by IDAutomation.com, Inc. of Tampa, Fla. and described at the URL corresponding to idautomation.com/datamatrixfaq.html which is hereby incorporated by reference in its entirety. Various embodiments of the facility incorporate a variety of symbol generator modules, such as the Barcodesoft Data Matrix Encoder available from Barcodesoft of Scarborough, Ontario, Canada at the URL corresponding to barcode-soft.com/contact.aspx. The server permits a user of the browsing client to create a new discussion, upload content for the discussion into the content store, and use the symbol generator module to generate a symbol identifying the discussion. The user can then make rendered copies of the generated symbol available for other users of the community to capture using a capture client 2440.

The capture client, such as a cellular phone, PDA, etc., has installed on it a capture program 2441 available from the community website. A user of the capture client executes the capture program to use an optical sensor 2442 included in the capture client to capture an image of a rendered symbol representing a discussion, decode the symbol, and take some action in response. For many discussions, the capture program uses a wireless network 2450 to send to the server via the Internet an indication that the user associated with the capture client has captured the symbol for a particular discussion. In some embodiments, this indication sent by the capture client to the server includes the user's user name to associate the indication with the user or another identifier for the user generated by or in connection with the facility. In other embodiments, the facility uses other information to associate the indication with the user, such as the telephone number of the phone, or a hardware identifier or serial number of the phone or a component thereof. When the server receives the indication, it stores the indication, which is then available both via the user's user page, and via the discussion page for the captured symbol. In some embodiments, the user may use the capture client to go on to immediately participate in the discussion corresponding to the captured symbol. In cases where the capture program is used to capture a symbol having contents that are immediately actionable by the capture client, the capture program automatically causes this action to proceed, or prompts the user as to whether the user wishes this action to proceed. For example, where a telephone number is encoded in a captured symbol, the capture program causes a telephony interface 2443 of the capture client to dial the telephone number. Similarly, where the symbol encodes an email address, the capture program causes an email program 2444 installed on the capture client to address a new email message to the encoded address. Also, by virtue of the fact that' the captured symbol and its discussion is noted by the facility on the capturing user's user page, the user may instead visit that user page at a future time, using either the capture client or the browsing client, to take actions associated with the symbol and/or its discussion.

FIG. 25 is a block diagram showing some of the components typically incorporated in at least some of the computer systems and other devices on which the facility executes. These computer systems and devices 2500 may include one or more central processing units (“CPUs”) 2501 for executing computer programs; a computer memory 2502 for storing programs and data-including data structures, database tables, other data tables, etc.-while they are being used; a persistent storage device 2503, such as a hard drive, for persistently storing programs and data; a computer-readable media drive 2504, such as a CD-ROM drive, for reading programs and data stored on a computer-readable medium; and a network connection 2505 for connecting the computer system to other computer systems, such as via the Internet, to exchange programs and/or data-including data structures. In various embodiments, the facility can be accessed by any suitable user interface including Web services calls to suitable APIs. While computer systems configured as described above are typically used to support the operation of the facility, one of ordinary skill in the art will appreciate that the facility may be implemented using devices of various types and configurations, and having various components.

A description of the user's interaction with the community in some embodiments of the facility follows.

A user signs up as a member of the community using its website. The user is sent a sign up confirmation code to the phone number entered. Upon receiving the code on his or her mobile phone, the user enters the code on the site.

The user then downloads the Smartpox phone application to his phone. Upon successful installation the user runs the application and is prompted for his user id. His member id was generated by the facility based on his profile at the community website.

After entering his 6-digit member id on his phone, the Smartpox phone application restarts and is now fully personalized based on the user's site profile.

When the user spots a Smartpox code out in the world, the user launches the Smartpox phone application and decodes the Smartpox with the phone reader. When the phone detects a Smartpox code, it will prompt the user with options based on the kind of data that was encoded from the community website.

The type/kind of data can be summed up in 2 approaches: 1) The data is presented upon successful decoding; 2) The user is given the option to ‘tag’ the decoded data to his or her user page at the community website.

If the type of data is ‘static,’ the facility displays it directly on the phone, without the need to go online to retrieve the remaining data or personalized data.

When the user selects the option to ‘tag’ this data to his the community website profile, the user's phone will connect to smartpox.com and verify the user's member id and link the data from the user's phone with the data on the site. The user will then be giving the option to view to content/data or to disconnect.

At any/all given times, the community website is aware of exactly who ‘spotted/captured/decoded’ data that was linked back to the community website from the members phone. This is due to the Smartpox client having been paired with the members profile on the community website. The phone client has the capability to both push and pull data personalized or anonymously from the community website.

The client can be installed directly from the phone or my transferring it from the user's laptop/desktop workstation after the user downloads it.

In some embodiments, the facility can present advertising messages to a user based on the set of symbols that the user has captured, other actions performed by the user in connection with the community generated by the facility and/or user registration information. For example, a user who has captured a symbol relating to an ultimate Frisbee tournament might receive an advertising message promoting a new flying disc model; a user who has captured a symbol relating to a gourmet cooking group and who has selected San Francisco as his or her locale during registration may receive an advertising message for a San Francisco kitchen equipment store; and a user who has captured a symbol for a Shinto discussion group and commented in a discussion about anime may receive an ad for Japan travel services. The facility may present these ads via the capture client, within the context of the community website, or via some other channel. The facility may present advertising messages directly in response to a user action that qualifies the user to receive an advertising message, or at some later time.

In some embodiments, the capture client generates and/or displays its own symbols, for capture by another user of the community, or by a related party such as a cashier at a store. In some embodiments, the facility uses this capability to generate machine-readable coupons, admission tickets, arcade credits, etc. on a user's behalf.
